摘要:

依据气承式膜结构成型原理和火灾危险性,以某气承式膜结构建筑为例,针对 PVC 材料气承式膜结构在实际应用中的技术难点,开展火灾工况下的结构响应分析,计算不同场景下的膜面应力和最大位移。在膜材燃烧实验基础上,设定最不利火灾场景,计算膜结构附近的最高温度,提出防火设计方案并验证方案的可行性。

Abstract:

According to the air- supported membrane forming principle and fire risk,taking an air-supported membrane building as an example, in view of the technical difficulties in the practical application of PVC air-supported membrane structure, the structural response analysis under fire condition was carried out to calculate the membrane surface stress and maximum displacement under different scenarios. Based on the membrane combustion experiment, the most unfavorable fire scenario is designed. Calculate the maximum temperature near the membrane structure, put forward the fire protection design scheme and verify the feasibility of the scheme.
